;;; test-calendar-sync--calendar-url.el --- Tests for feed URL resolution -*- lexical-binding: t; -*-
;;; Commentary:
;; Unit tests for `calendar-sync--calendar-url', which resolves the .ics
;; feed URL for a calendar plist. An explicit :url wins; otherwise the
;; URL is looked up in auth-source (e.g. ~/.authinfo.gpg) under the
;; calendar's :secret-host. auth-source-search is mocked at the boundary
;; so tests never touch disk or GPG. Covers Normal, Boundary, and Error.
;;; Code:
(require 'ert)
(require 'calendar-sync)
(defmacro test-cs-url--with-auth (result &rest body)
"Run BODY with `auth-source-search' stubbed to return RESULT.
Records each call's :host argument into `calls', a binding BODY can read."

(push (plist-get args :host) calls)
